By all means feel free just to chat in the guestbook - as long as it's not spam!

Anybody with Admin below their name is definitely me or a trusted person. I myself will always sign as Butterfree. If somebody signs under that name but does not have the Admin label, it is most likely an impostor.

Same reason you need an e-mail address on almost every place on the internet where you can make an account: it makes it harder for spammers and trolls to create duplicate accounts to spam or evade bans, and it makes it possible to have features like password recovery.

If you need an e-mail address, you can simply make one; there are lots of sites where you can sign up for a free e-mail account, such as Gmail (Google's free e-mail service).
